大连机床厂为了提高热轧和滚齿后的齿轮精度,进行了冷轧齿轮的试验。 冷轧是在径向进给的热轧齿轮夹具上换上一付冷轧辊后进行的。轧时的主轴转数为100转/分,进给量为0.05～0.1公厘/转。正转、反转各30秒。冷轧辊的几何精度符合 6512-53二级齿轮标准。冷轧前齿轮齿形座留约为0. Dalian Machine Tool Plant in order to improve the precision of the hot-rolled and hobbed gear, the cold-rolled gear test. Cold rolling is done by placing a pair of cold rollers on a hot-rolled gear fixture that feeds radially. Rolling spindle speed of 100 rev / min, the feed rate of 0.05 to 0.1 mm / rev. Forward, reverse the 30 seconds. Geometrical accuracy of cold roll conforms to 6512-53 two-stage gear standard. Before cold-rolled gear toothed left about 0.
